Swallow. The Purple worm makes one bite attack against a Medium or smaller creature it is grappling. If the attack hits, the target is swallowed, and the grapple ends. The swallowed target is blinded and restrained, it has total cover against attacks and other effects outside the frog, and it takes 7 (2d6) acid damage at the start of each of the Purple Worm’s turns. The purple worm can only have one target swallowed at a time. A creature can escape by doing 20 points of slashing damage from a light weapon (one attack each round, automatically hits). The muscles in the purple worm’s abdomen immediately close such holes behind an escapee. If the purple worm dies, a swallowed creature is no longer restrained by it an can escape from the corpse using 5 feet of movement, exiting prone.
